M invention concerns a shaving brush the han le of which is adapted to contain a certain quantity of past soap`or shaving cream. One of the objects o my invention is to provide a shaving brush of that ty e whose handle contains a discharge device t rough which it is ossible, by merely pushing or depressing t e extremity of the handle, to feed mto the tuft of hairs of the shaving brush, a predetermined small quantity of soap or cream.

That arrangement revents any clogglng of the tuft of hairs t at might result from feeding too much of soa into the tuft of hairs. Furthermore, the eeding device ma be operated while holding the shaving brus in one hand, so that the discharge of the soap or shaving cream ma take place While lathering the parts to be s aved.

i 15 is a plan view showing a detail of the s iding extremity of the handle. Asshown in Fig. 1 of the drawings, thehandle of the shaving brush comprises a main cylinder 1 in which a piston 6 rovlided with a packing ring 7 1s adapted) to s 1 e.

view corresponding to A tube 3, secured to the bottom of said ma'n 75 cylinder, forms the cylinder of the discharge device, and is provided with holes a. A cylindrical rod 8, which forms the'piston of the discharge device, and is made integral with cap 9, is adapted to slide in said tube 3. A spring 9L is disposed between the bottom of the cap and piston 6. A sleeve 4 secured to the lower end of tube 3 supports an Indiarubber nipple 5 acting as a kind of check valve. To this effect the end of said nipple is slit, so that, when a certain pressure 1s exerted inside it the edges of the slit are material contained in said nipple is ischarged through said slit, while any counterpressure strongly applies the edges of the slit against each other, thus tightly closing the mpple. When cylinder 1 is full of shaving cream, the spring, acting upon (piston 6, urges it in an outward direction an thus tends to force shavingcream into tube 3 throu h holes a. Said tube is thus filled up to the c eck valve or nipple. When cap 9 is depressedbyethe alm of the hand, the 4body of the brush ing eld with the fingers of the same hand, the

small piston 8 is forced into tube 3 which drives out a predetermined quantit of soap or shavinglcream through the slit o nipple which is t us opened and allows said soap or shaving cream to penetrate into the tuft of hair 10 of the brush. When cap 9 is no longer depressed, piston 8 is brought back to its initial position, and the whole of the device is in the same position as at the beginning, so that the above described operation can be repeated until cylinder 1 is empty.

It will readily be understood that the embodiment above described can be modied without departingfrom the principle of the invention. In particular, spring 9 might be so arranged as to rest, not on iston 6 but on a stationary part 1 of handle 1. uch an arrangement is disclosed in Figs. 1a to 15, concerning another embodiment of my invention. The spring will then serve onl to bring cap 9, which forms the movable ottom of the handle 1 of .the shaving brush, back to its initial position, and the lling of the extremity of tube 3, and of nipple 5, will take place, after each stroke of push piece 9,

Y through the action of the vacuum created by the backward motion of rod 8.

In said second embodiment, vthe shaving brush comprises a cylindrical tube or body 1, closed, on the one hand at its upper part, by an end piece 1b integral with cylindrical body 1, and provided with a tube or nozzle 1 upon which India-rubber nipple 5, acting as a check valve, can be fitted, saidbody 1 being closed on the other hand, at its lower part, b a movable piece 11 shown in detail in igs. 8 and 9, and the circular edge 11"L of which is applied against the edge l (Fig. 6) of cylindrical body 1. Said piece 11 acts as a rest for spring 9a provided in the cap or push piece 9 for moving the latter outwardly as soon as it is no longer pressed upon. The rod or plunger 8 which moves inside cylindrical body l is secured to the bottom of the cap or push piece 9. A guiding and packing ring 12 is adapted to slide along said u rod 8, but it may be temporarily wedged on said rod, at the end thereof, upon a conical portion 8b, when the shaving brush is being replenished, as will be hereinafter described.

The connection between cylindrical body 1 and cap or push piece 9 is obtained through a bayonet joint. To this effect, the edge 1 (Fig. 6) of cylindrical body 1 does not run along thewhole periphery of the latter, but forms two sorts of lugs la. The same is true of the edge of cap 9, which forms two lugs 9c (Figs. 7a and 15), the interval between which corresponds to the length of lugs 1*. Under these conditions, tube 1 may be engaged into cap 9, by pushing back movable piece 11 against the action of spring 9a. Then, by rotating cap 9 through a certain angle with respect to tube 1., orinversely by rotating tube 1 with respect to cap 9, lugs 1 and 9 are brou ht opposite each other, which connects the tue with the cap, while allowing the -latter to slide along the tube.

During that sliding motion, movable piece 11 is guided along vertical partitions 14, which engage diametral notches 11d, provided to this effect (Fig. 8) in the edge 11a of movable piece 11.

In that position, which is shown in Figs. 7 and 7a, the semi-cylindrical ribs 13, diametrally located along edge 1a of body 1 engage corresponding semi-cylindrical grooves or housings 11 provided in the edge 11a of piece 11 so that body 1 is held in position with respect tocap 9.

By furtherrotating cap 9 in the direction of arrow F (Fig. 7) with respect to body 1, I ensure the locking of tube l with cap 9 in the longitudinal direction, due to the fact that the extremities 1b of lugs 1 engage notches 15 provided in the vertical partitions 14 carried by cap 9, and are therefore maintained between the upper face 9c of cap 9 and the horizontal edge l5a of notch 15 provided in vertical member 14 (Fig. 4a). It is that position that is shown in Fig. 1a.

In order to limit the amplitude of the rotation of tube 1 with respect to cap 9 and to avoid that lugs 1a may unwillingly be rotated as far as the interval provided between lugs 9c (Fig. 15) of the cap, which would result in unlocking the body or reservoir 1 0f the brush from the cap, I have provided 0n lugs 1"1 a small projection 1d which is adapted to butt against the edge 14a of member 14 (Figs. 4 and 4a).

Furthermore, in that position, ribs 13 are engaged into the grooves 11b of movable piece 11, which ensures th good positioning of the parts. f

The passage of rib 13EL from groove 11b (locking position) to groove 11c (position or which the cap or push piece 9 is adapted to slide freely with respect to body 1) is made possible by the elastic mounting of piece 11 at the end of 'tube 1. In the case of tube 1 containing no soap or shaving cream, tube l may be locked with respect to cap 9 in the position in which it is fully engaged therein (Fig.I 3). The edge 1a of body 1 is then brought, through relative angular displacement of the body and of the cap, under offsets 16 provided at the lower part of members 14 (position of Fig. 3).

My invention also includes the particular arrangement of the India-rubber nipple and the setting of the tufts of hairs of the shaving brush in a ring, which features will be hereinafter described.

Nipple 5, which extends into the tuft of hairs 10 of t-he brush and can be bent at the same time as the hairs when the shaving brush is being used for lathering, is protected by a ring 17 which surrounds the lower part of said nipple and which is provided,

at its lower part, with s. fiat ring 18 ajplied plained by causing rib 13 of edge 1a of body upon the u per face of the base or ange 1 to pass intovgroove 11" of movable piecev 5a of thefnlpple. Said flange is provided, as shown in F1gs.'10 and 11, with two radial notches 5" provided in its thickness and which are adapted to fit upon ribs 1f provided on the upper end 1" of cylindrical body 1. Said'ribs 1 form two oblique`channels through which a dose of soap or shaving cream m is allowed to pass, in the direction shown by Fig. 1a, fronr the cylindrical body into the nipple.

Finally, the hairs forming the tuft of the shavin brush are held at their lower part by a rmg or sleeve 19, the upper edge 19 of which projects inwardly and which is screwed at 19b in a member 20 which is for instance soldered to cylindrical tube or body 1 u on the upper face lb thereof.

he operation of the sha-ving brush whichv has just been described with reference to Figs'. la to 15 is as follows:

In order to ll cylindrical tube or reservoir 1 with pasty soap or shaving cream, cap 9 and cylindrical tube or reservoir 1 are separated from each other by means of the bayonet joint, which disengages said'cap and its rod 8.

A certain quantity of pasty soap or shaving cream is then introduced into cylindrical body 1 and after pushing ring 12 as far as the end 8b of the rod, where it is slightly wedged, the cap is again fitted into osition by inserting rod 8, which is guided y'ring 12, in to cylindrical body 1. Said ring first presses down the soap or shaving cream until the latter forms a homogeneous mass without any air present therein, and then it slides back along rod 8 as said rod is being engaged into the cylindrical body. Ring 12 then acts as a packing ring. Tube 1 and cap Y9 are then connected to each ,other through the bayonetV joint and the cap is moved with respect to the tube or body until rib 13a engages groove 11C. The shaving brush is then ready to be used and it suffices to hold the body 1 of the shaving brush between the thumb and the foreinger and to depress cap or push plece 9 with the palm of the hand or with the thumb for discharging into the tuft of hairs l() of the shaving brush the quantity of soap or shaving cream contained in nozzle 1c and nipple, or check valve 5.

When push piece 9 is released, it is brought back to its original position by the action of spring 9EL and the backward movement of rod 8 allows a fresh quantity of soap or shaving cream to be forced into nozzle 1c and nipple 5, in the direction. of arrow f.

According to the quantity of soap or shaving cream which it is desired to use for lathering, push piece or cap 9 may be depressed one, two `or three times.

It is then possible to lock cap 9- with respect to cylindrical body 1 as it has been above ex- 11'and'to lather ones face exactly as with an ordinary shaving brush. During the operation, packing ring 12l ensures the tightness of body or reservoir 1.

While I have disclosed `what I deem to be `practical and efficient embodiments of my invention, it should be well understood that I do not wish to be limited thereto as there might be changes made in the arrangement, disposition and form of the parts without de.
